Police in Vietnam's central Quang Binh Province seized 1.4 tons of precious Sua timber from two trucks on a street Wednesday, believed to have come from three trees illegally logged at the Phong Nha-Ke Bang National Park.

It is not known how the timber made its way out of the park.

The trees were felled in early April, and forest rangers said it has been hard for them to protect the timber from armed loggers and mobs of locals entering the forest to grab pieces of wood.

The police said they seized more than 600 kg of wood at around 6 p.m. from a truck owned by Tran Thi Hoa, 41, a local.
